Newlandsmuir Sand Mastic
Traditional burnt sand mastic around sash and case windows and doors in stone and brick for homes and businesses in Newlandsmuir and across South Lanarkshire. Fully insured, ARBOMaster approved and guaranteed for a year.
- Tired mastic found when preparing windows for paint

- Draughty sash windows at the surround
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Do not run silicone over sand mastic
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
- Ask us before painting near the mastic
Keep paint scrapers and sanders off the mastic when redecorating. It can be damaged by heavy scraping.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber, which can lead to rot.
Sand mastic in Newlandsmuir, done properly
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on period & listed homes, brick reveals and sash and case windows, and people most often call us about mastic dropping out of the joint and mastic that needs renewing before redecorating.
Mastic can only go onto a dry joint, so outside work in Newlandsmuir depends on the weather. Let us know about access to every frame, including any upstairs.
You’re covered for a year from the day we finish. If there’s a problem with it, please drop us a line at info@mrmastic.co.uk.

How we quote for sand mastic
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Whether old sealant or filler has to be cut out
- Mould in or behind the old joints
- How easy the joints are to reach
- When we can work, for business premises
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- Roughly how big the job is
- Where the property is
- If someone has resealed it before
- A few pictures by email, if you can
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear quote for your job. To get started, send an email to info@mrmastic.co.uk.
Frames and glazing around Newlandsmuir
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that. Newlandsmuir is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.
Schools such as Duncanrig Secondary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.

What else we do in Newlandsmuir
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Do you need sand mastic in Newlandsmuir?
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Signs it’s time to call us include:
- Draughty sash windows at the surround
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
- Gaps where the frame meets the masonry
Rented homes near Hairmyres station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Brick reveals
An open joint at a brick reveal lets weather in. Renewing the mastic closes it.
